The invention belongs to the technical field of extraction and qualitative and quantitative analysis of substances, and the invention provides a method for detecting volatile components of a tomato ora product thereof. The method for detecting the volatile components of the tomato or the product thereof comprises the following steps: a) extracting the volatile components of the tomato or the product thereof by using solid-phase microextraction; b) extracting the volatile components of the tomato or the product thereof by using a solvent-assisted flavor evaporation method; and c) using gas chromatography-mass spectrometry to detect the volatile components extracted in step a) and step b separately; collecting the detection results, and removing the repeated components, so as to obtain thevolatile components of the tomato or the product thereof. The method for detecting the volatile components of the tomato or the product thereof realizes the maximization of the extraction of the volatile components of the tomato or the product thereof by combining the solid-phase microextraction and the solvent-assisted flavor evaporation method.
